Project Sigma
As a direct result of uniLab work, they have developed darts designed at the outset with barrel shaft and flight all mathematically matched to form an optimum aerodynamic unit, specified to give true flight and greater accuracy.

These Sigma Pro side load darts shafts are specially designed replacements for the Sigma Pro Darts.

They can also be used with any other darts.

They are supplied 3 for £6.00
